摘要

本文提出了一种用于图像恢复和增强任务的新型冲击滤波器。该方法是用一组偏微分方程来描述处理后的图像及其光滑二阶导数的演化。该方法采用鲁棒扩散方向上的选择性平滑项，并通过实验在真实图像和合成图像上验证了其有效性。

A novel shock filter for image restoration and enhancement

The paper proposes a novel shock filter for image restoration and enhancement tasks. The method is put in terms of a system of partial differential equations that describes both the evolution of the processed image and of its smoothed second order derivative. The method employs selective smoothing terms acting on robust diffusion directions and its efficiency is proven in the experimental part of the paper on both real and synthetic images.
